Math modelling suggests may take as few as ten virions for someone to become infected with SARS-CoV-2.

Order of magnitude more infective than SARS.

Also blows up the 6 foot rule. Those babies from that stupid 1981 study gonna be upset.

That would be BANG on this dose response for SARS-CoV-1

pic here
Modelling shows droplets represent FAR LESS of any spread than the small aerosols.

Just on the NUMBERS it is the SMALL AEROSOLS that matter.

There is NO MINIMUM TO INFECT.

This is a STATISTICAL process.

As dose goes up you have MORE CHANCE to be infected.

ID50 for SARS-CoV-2 in Syrian hamsters = 5 virus particles to make an infection 50% of the time.

Close to the ten found for humans.

This is how ALL RESPIRATORY PATHOGENS work - release many many into the air and very few stick and cause infection.

Same with pertussis, strep, rhinovirus and RSV (despite stupid "touch" being predominant in the stupid literature)

They do GAIN OF FUNCTION experiments on animals for goodness sake. They snip the virus and see if they can "make it airborne".

It ain't growing wings. It's being made MORE infectious!

This is also why RCT mask wearing is deadly for NO GOOD REASON.

INFECTION IS A STATISTICAL PROCESS AND THERE ARE TOO MANY CONFOUNDERS LIKE THE MASK SLIPPING FOR ANYTHING EXCEPT THE CRUDEST RESULTS TO BE DRAWN FROM THEM.

DO NOT RCT MASK. IT IS STUPID.

Finally explaining increased infectiousness, see Wolfel, from April 2020, that found perhaps a cleavage site led SARS2 to become more infectious in upper resp tract, thus breathing out particles before you get seriou symptoms. April 2020.

But hey now that we are into variants probably all kinds of increased binding strength/ability happening now, driving dose response down, but we'll have to wait and watch

Enjoy your Friday

It's in the air

It ain't the droplets, bro

Dinosaurs, begone.

Oh hey flu is also in the air here's air experts writing a paper so I trust it. @Don_Milton @CathNoakes and others.

Oh here it is.

biorxiv.org/content/10.110…

Through genetic variation see that bottleneck in infection means about 1-3 viruses make the jump.

Math modelling 10. Genetic modelling 1-3. Not bad for such itty bitty things that we discovered in the 1920s.

19 person outbreak at the Public Health Ontario labs.

Same PHO that says surgical masks just fine.

Same PHO that wrote that biased snobby and insulting summary of the aerosol conference in November.

Can't even make this stuff up.

"Wondered"?

Whether "community spread" or whether "somehow acquired through an infection from laboratory tests itself"

I'll tell you where from ...

"I think this is an airborne virus and it's more infectious than we give it credit for"

My God, it's full of stars. Image

Magic measles spreads just like COVID-19.

Imagine that.

Childcare, home, etc major settings.

Of course contact, because you need to at some point be near a sick person, but 40% unidentified locations.

nejm.org/doi/full/10.10…
Not all that useful, but this is the data we get in Toronto:

Ppl can do their own research since it ain't me saying droplet for one BREATHOUTABLE virus and airborne for magic measles.
And this is how stupid this debate is.

Lancet in 2017 says measles "predominantly" droplets.

On the airborne argument, fundamentally the reason they won't agree to ever change.
From UK IPS
Note the concern with breaking ranks from national guidance, which of course would apply similarly at national up to international level.

I rarely bother with her tweets but this one is correct.

It is vaccines AND adjusting their view of the science to aerosol (the truth) that will help get to minimal cases.

Unfortunately the WHO committee system appears to be broken, and its advice negligent.

#COVIDisAirborne
Never in my wildest imagination would I have thought during a global pandemic the people holding the world up would be the infectious disease doctors and the WHO,

And by dismissing the actual laboratory scientists who do this work.

Crazy.
Well we've shown how this has been going on for 120 years and founded on nonsense

Absolutely everything points to air

Scientists say air

Math modellers say can only be air

Epi data properly interpreted (or if you don't lie about it) says air

Other viruses in air

It's in air

Well that's it for the WHO's reputation.

It shot itself here.
CBC reporting on WHO advisor not providing masks because of acne

That was today.

BUT ALSO this also just came out, where WHO funded four reports which surprisingly (really, not) said no air spread. Those reports connected to virus downplayers/deniers.

And what committee wrote that?

And who wrote the August article from the committee?

And who presented recently?

And now we have four more garbage review articles coming out, funded by WHO, that say "more evidence needed"?

This is like climate denial.
... No amount of evidence seems to suffice.

Move past the naysayers and carry on.
Oh no.

Would you look at that. Conflicts and funding from the WHO to downplay aerosol spread.

Well, every litigation file just got a whole lot easier.
